kleines Filmröllchen 98c0c5e9e6 Help+Base: Add help://man URLs for links between man pages 
The URLs of the form `help://man/<section>/<page>` link to another help
page inside the help application. All previous relative page links are
replaced by this new form. This doesn't change any behavior but it looks
much nicer :^)

Note that man doesn't handle these new links, but the previous relative
links didn't work either.
